Tech. Peripherals and Accessories

Peripherals are external devices that are connected to the computer to enhance performance or make interactions easier. Some of these, such as a mouse and keyboard, are very common. Others that have very specific uses may not be as well known.

Most of these devices are connected to the computer either wirelessly, or directly by a USB cable.

If you need help with any of the terms used below, you can check out our definitions page by clicking HERE.

Mouse - A small device which is connected to the computer in order to manipulate the user interface. Fits in the hand of the user and usually has two buttons that sit under the finger as well as a wheel for scrolling.

Keyboard - Device used for inputting letters and numbers on a computer. In addition to this, most keyboards have special keys that can be used for a variety of functions. If you'd like to learn more about these, click HERE.

Monitor - The monitor is a screen on which the computer displays its information. On a laptop, this is built in to the device. For a desktop, it needs to be connected externally and requires a separate power source.

Printer - This device produces physical copies (prints) of on-screen items. While it's not used frequently for online schooling, it may be required for some assignments and can assist some students who work well with printouts. A printer is provided to all families enrolled at Agora.

Dongle - Small device that inserted into a USB port that allows a device to connect wirelessly. A wireless mouse or keyboard usually requires a dongle to operate.

Ethernet Cable - This is a networking cable that looks similar to an older phone cable. You will likely need one to connect your modem and router. It can also be used to connect your computer, laptop, or other peripheral directly to a networking device. For more information on Networking Basics, check out our page HERE.

HDMI Cable - This cable type is typically used for connecting television components but can also be used to connect monitors to computers.

Printer Cable - This is a form of USB cable (USB-B) that has a standard USB-A connector on one end, but more of a 'square' connection at the other end. This type of cable is becoming more obsolete, but many printers (and other peripherals) may still have this connection. If your school-provided printer needs this cable, you will be provided with one.

USB - Universal Serial Bus cable that forms the standard for most computer connections. There are several types of USB connections as you can see in the picture below.

• USB - A: Standard rectangular end that usually connects directly to the computer or laptop.
• USB - B: More of a square end. Sometimes called a 'printer cable', though other peripherals may use this as well.
• USB - C: Current standard for USB connection and charging cables. Most newer devices will use this type of connection and it has even replaced the USB - A end of many cables and computer ports.
• USB - Mini: Older standard connection and charging station. Meant to make the connection smaller, but odd shape created somewhat difficult connection.
• USB - Micro: Older standard similar to Mini, but slightly smaller.

This section simply defines basic networking peripherals. For more details on how they work, check out our Networking Basics page HERE.

Modem - A device that receives and sends internet signal. Usually connected directly to your Internet Service Provider (ISP).

Router - A device that distributes internet data to multiple devices throughout your home. Usually connected directly to a modem or as part of an all-in-one unit. Can provide wireless signal (wifi) to an area. Routers typically have antennas.
